What a difference 24 hours can make.
Maybe I should have waited before making my last post.
This morning I went to a doctor who specializes in veinology, or whatever the art is called. The first specialist I’ve been able to see. I was scanned again, and the blood clot is gone. Without a trace.
So all I have to do is keep taking the blood thinner for another couple months, to prevent the condition from returning, and then I’m free as a (slightly limping) bird. I feel lucky, both in my health and in my friends.
